(AP) - Fire crews in Northern California have been battling a series of devastating wildfires, including the so-called Carr Fire near the city of Redding and the Mendocino Complex fire.

The 206-square-mile Carr Fire, located about 100 miles south of the Oregon border, has destroyed more than 1,060 homes and many other structures. Two firefighters have died there.

And forecasters say the threat of major fires will remain high across much of California and the northwestern corner of the U.S. throughout August and September. The National Interagency Fire Center's monthly outlook says lightning, drought and an abundance of dry trees and vegetation combined to produce above-normal chances for major wildfires in the region.
